NGC6572 is a rarely imaged planetary nebula, probably because it is very tiny, just 12" x 5" (arc seconds) in size.
It is exceptionally bright and just presents like a star in small scopes.  Large scopes like my CDK20 can show some shape like my image here.
However, this object has exceptionally nice detail, but the only way to obtain it with amateur equipment is to image it like you would one of the planets, many very short images to minimize the effects of seeing.  My image is 700 short images of 1 second each, not nearly short enough to get much detail.

This very fine example by Exaxe used 72,000 images at 0.2 seconds each on an Orion Optics 300mm.

The process for this requires very small images that don't have enough stars for PixInsight to register the images, so you must use planetary imaging software to register them.
Try as I might, I never succeeded in figuring out how to get that software to work for me.

Some processing suggestions by Exaxe has resulted in bringing out some detail that did not appear in the original attempt.
Thanks Exaxe.

NGC 6572 is a planetary nebula in the constellation Ophiuchus. It was discovered in 1825 by the German astronomer Friedrich Georg Wilhelm von Struve. According to several sources such as Sky & Telescope, this object received the nicknames Blue Racquetball, Emerald Nebula, Green Nebula, and Turquoise Orb.[[i]citation needed] At magnitude 8.1, NGC 6572 is easily bright enough to make it an appealing target for amateur astronomers with telescopes. At low magnification, it will appear to be just a colored star, but higher magnification will reveal its shape.

NGC 6572 is a relatively young nebula, and began to shed its gases a few thousand years ago. Because of this, the material is still quite concentrated, which explains its abnormal brightness. The envelope of gas is currently racing out into space at a speed of around 15 kilometres per second. As it becomes more diffuse, it will dim. Its structure consists of two bipolar shells that are slightly misaligned from each other's axes, as well as a toroidal waist.

The central star of the planetary nebula has a spectral type of Of-WR(H). The central star has an effective temperature of 68,000 K and a luminosity about 5,700 times that of the Sun.
